LM9072
Dual Tracking Low-Dropout System Regulator
General Description
The LM9072 is a high performance voltage regulator system
with operational and protection features that address many
requirements of automotive applications. Two regulated out-
puts are provided. The main regulator provides a precision
2% maximum tolerance 5V output at 350 mAwith a low drop-
out characteristic. The second regulator provides a 5V out-
put that tracks the main regulator output voltage within 1.5%
with load currents up to 80 mA. The tracking output is ideal
for use in powering remotely located sensors with outputs
that are ratiometric to the main system supply. This output is
fully protected from short circuits to ground or the unregu-
lated input supply (ignition or battery potentials in automotive
applications).
The LM9072 also contains a programmable delayed system
reset output. Two control inputs are provided.An ON/OFF in-
put intended for connection to an ignition switch, and a Keep
Alive input to allow a system to remain powered after ignition
has been switched OFF.
For EMC concerns the LM9072 remains fully operational
and does not generate false rest signals while subjected to,
1 MHz to 400 MHz bulk current injection signals greater than
100 mA on the input supply and tracking output lines.
